to me the wheels need to be physcial, it’s hard to find all those knobs while playing and not looking at it – same problems when performing with my iPad – I do – but I need to have my eyes on that pad – knobs and wheels – give some feedback- but that display is awesome in style.

reminds of „Plex“ vey simple change in a circle, it’s not too much of „changing“ it but… have a look at the video:

2x LFO, 2 Channels mit/with OSC-Filter-AMP – not the same filters – it’s LPF on one, HPF on the other channel – ADSR instead of CS80-type-Envelopes, so no CS rather than an RSF – makes 2x ADSR – and modmatrix and VCO wave morphing /seamlessly.

Polykobol is an exotic polysynth from france – there are 50 of it around (Version I and II) and there is a software clone called the PolyKB by Xils-Lab. But only the nerd knows who RSF were and their monophonic Kobols are more known than the poly – but they finally did a clone, not RSF but some people in Japan, called Black Corp.
